The only commercial caster using my lube at present is Montana Bullet Works, but their bullets are hand cast and sized, which demands a premium price, up there with jacketed, I believe. But they WILL outperform jacketed. Probably more than you want to pay.
The simplest fix if to purchase a couple sticks of our blue soft solid lube, which is much like modeling clay in consistency at room temperature. Wipe just a little off the stick with the index finger of your master hand, then smear it very lightly over whatever lube the commercial caster is using. In most cases your leading problem will go away and accuracy will improve. Lube won't improve poorly made bullets, of coarse, so stick to the bullets you are now using with satisfactory accuracy.
All shooters need to understand the hard facts of commercial bullet casting. They sell their bullets almost as cheaply as you can buy the same alloy, and make their profit on the difference in wholesale lead bought in large volume and retail lead in small volume. Since very few of their customers understand a thing about cast bullets or how to make them work, and because they operate on a shoestring budget, they use the cheapest lube they can buy. Those who can't live with the performance start casting their own. Those who are content with a loud bang and holes somewhere on the paper most of the time, buy commercial cast. (That last is a bit slanderous to many commercial casters who do turn out good quality, but don't realize how important good lube is.) (May I make this real clear. Slander is a visious lie, and I don't do it, but I do want to drive a point home.)
The little smear of LBT lube will make the well cast commercial cast shoot very well in most cases. If they are undersize and allow blowby, (which causes leading) but playing with powder charges till you get the bullet bases to obturate will normally fix that problem. In other words, if you still have leading with LBT added, and your loads are mild, up the charge to max in the manual you are using.
